ISO - casserole for sick friend

Hi Mommies! I have a friend who is sick and wanted to take a casserole. I am looking for something that can be placed in the freezer in case they don't need it right away. Easy to reheat and still yummy. Something that can be put in a foil pan. Any ideas? Thanks!Monica ETA - I am a decent cook, but I know nothing about freezing stuff. For some reason freezing things makes me nervous. Like it won't taste good reheated. Any tips? I'd like to freeze some meals for us too so I can have stuff on hand for days when I'm tired from work.

My favorite reheated dish it tator-tot casserole. I take a pound of hamburger and fry it with an onion, a few carrots and green pepper. Drain off fat. Add a can of cream of chicken and a can of cream of mushroom and add a can of corn and a can of green beans. Put into a 9x13 pan. Layer tator tots on top and cook according to the tator tot packages. So yummy and great reheated.
